BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a water purifier, and in particular to a low-noise vibration-reduction water purifier and method of installing the same.

2. The Prior Arts

Presently on the market, pump of water purifier adopts a side fixing approach to fix it on a wall. In this structure, plastic pad is placed between a pump and the fixing piece, to absorb and reduce vibration. However, this way of fixing is not ideal, for it can not eliminate the noise caused by vibrations of a pump.

The noise produced by the water purifier while working can be mainly attributed to two causes. The first cause is the mechanical noise produced by the pump in operation, this type of noise is rather difficult to eliminate. The second cause is the noise caused by the collisions of the main body, the water input tube and the water output tube, and other components in the pump while it is working. The existence of the noise mentioned could cause discomfort to the user.

Therefore, presently, the design of the water purifier is not quite satisfactory, and it leaves much room for improvement.
